基本错误缺乏高质量证据支持证据确定性: 中初步 C-VEG-16

回避（几乎）所有蔬菜、沙拉和豆类与良好的健康是相容的。

安全提示: 去掉蔬菜和豆类可能导致膳食纤维、钾、叶酸和维生素 C 摄入不足。这对以下人群尤其值得关注：儿童（WHO 建议 2-9 岁儿童每天至少吃 250-350 g 水果和蔬菜，儿科学会建议从开始添加辅食起就加入蔬菜）、孕妇和计划怀孕的女性（叶酸与神经管缺陷的预防），以及高血压或肾结石患者。在没有儿科医生或营养师建议的情况下，不应以这种方式限制儿童的饮食。

简而言之: 这一说法基本错误：没有良好证据表明回避几乎所有蔬菜、沙拉和豆类与良好的健康相容，而一致的证据和 WHO 的指导都支持每天摄入这些食物；降低死亡率的益处有多大尚不确定，但营养素摄入不足的风险是有充分依据的，对儿童和妊娠期尤其如此。

结论: 回避几乎所有蔬菜和豆类，与大量一致的证据和 WHO 的指导相矛盾；对心脏益处的大小存在争议，但营养素摄入不足是一种真实的风险，对儿童和妊娠期尤其如此。

科学评估

基本错误 – 该说法的主要部分没有证据支持，或被严重夸大。

证据确定性: 中 – 进一步研究仍可能影响该评估。

1. 说法是什么？

A diet with almost no vegetables and no legumes is healthy.

2. 哪些内容可证实是正确的？

Specific vegetables carry specific, avoidable risks (bitter zucchini, contaminated produce, extreme juicing, infant nitrate).

3. 哪些内容是错误或夸大的？

Fruit and vegetables: RR 0.90 for all-cause mortality per 200 g/day (Aune 2017), with benefits up to 800 g/day; green leafy vegetables and salads were inversely associated with CVD and mortality. Fibre: 15-30% lower mortality and disease incidence at highest vs lowest intake; greatest benefit at 25-29 g/day (Reynolds 2019). Potassium (mainly from vegetables, legumes, fruit) lowers blood pressure in hypertension (indirect for vegetables: 20 of the 22 trials used potassium supplements) and is associated with 24% lower stroke risk (Aburto 2013). Legumes lower LDL (Ha 2014) and are associated with lower mortality (Zargarzadeh 2023). Vegetables and legumes are main sources of folate; folate needs are higher in pregnancy.

4. 哪些内容仍不明确？

Observational associations may be partly confounded: in UK Biobank, adjustment for confounders explained most of the raw-vegetable/CVD association (Feng 2022, I-VEG-107), and a Mendelian randomization study found no clear effect on coronary disease (Feng 2023, I-VEG-108). The exact harm of complete elimination has not been tested; a self-selected survey of carnivore dieters reported short-term wellbeing but high LDL cholesterol (Lennerz 2021, I-VEG-109).

5. 哪些研究支持该说法？

Very weak: Lennerz 2021 (I-VEG-109), a self-reported, uncontrolled survey of people on a meat-based diet. Feng 2022/2023 question the size of the cardiovascular benefit of vegetables but do not test elimination.

6. 哪些研究与该说法相矛盾？

Aune 2017; Wang 2021 (I-VEG-106: 5 vs 2 servings/day, mortality HR 0.87); Reynolds 2019; Aburto 2013; Ha 2014; Zargarzadeh 2023; Taylor 2009; Lietz 2026 scoping review (I-VEG-110: nutrient-deficiency and LDL risks of plant-free diets); WHO healthy-diet guidance (I-VEG-112); ESPGHAN 2017 (I-VEG-111).

7. 对德国和欧洲而言情况如何？

German (DGE) and EU guidance recommend daily vegetables and regular pulses (not fetched in this review).

8. 关于埃及的已知情况是什么？

In Egypt, vegetables and legumes are central, affordable sources of fibre, potassium and folate.

9. 合理的实际结论是什么？

对所有人排除蔬菜和豆类与证据不符；特定风险可以因人而异地加以控制。

评估详情

证据确定性的依据: Consistent dose-response cohort meta-analyses link fruit/vegetable and fibre intake with lower mortality, CVD and cancer; RCTs show causal effects of fibre, potassium and pulses on risk factors (body weight, blood pressure, LDL). No trial has tested total vegetable elimination, so certainty is moderate.
来源质量: Food lists (archive and third-party) and archive quote.
地区可推广性: Applies to Germany and Egypt.
个体例外情况: Temporary restriction of specific vegetables may be appropriate in IBS, certain bowel obstructions, potassium restriction in advanced CKD, or individual allergy.
说法的地域范围: 普遍性（生物学/医学）
最近审核: 2026年10月26日初步

原始文献

总体证据说明了什么？

基于上述研究的编辑评估——其本身并非研究结果。

哪种观点有更好的证据支持？

Diets meeting fruit, vegetable and legume recommendations are associated with lower mortality and better risk-factor profiles; diets largely without plant foods carry risks of fibre, folate, potassium and vitamin C inadequacy and of raised LDL cholesterol. No controlled evidence supports long-term safety of eliminating vegetables and legumes.

为什么有些研究权重更大

Large cohort meta-analyses (Aune 2017, Wang 2021; overlapping cohorts counted once), fibre SR/MAs with RCT components (Reynolds 2019), potassium and pulse RCTs (Aburto 2013, Ha 2014) and WHO/ESPGHAN guidance outweigh a self-reported survey. Feng 2022/2023 lower confidence in the size of the vegetable-CVD effect but do not address nutrient adequacy.

因果关系是否已确立？ 很可能 Causal effects are established for fibre, potassium and pulses on risk factors in RCTs; for vegetables and mortality, causality is probable but not proven (observational data, residual confounding).

仍存在的不确定性

Magnitude of the causal mortality benefit of vegetables specifically; no trial of total elimination exists.

合理的结论

The claim is mostly false: avoiding nearly all vegetables, salads and legumes is not shown to be compatible with good health and conflicts with consistent evidence and with WHO and paediatric guidance. It is a particular risk for children and pregnant women.

为什么研究结果看起来互相矛盾？

Feng 2022 (UK Biobank) and Feng 2023 (MR) suggest that the vegetable-CVD association may be largely confounded, whereas Wang 2021 and Aune 2017 find robust inverse associations with mortality. Differences: crude single-measure tablespoon intake vs repeated FFQs; CVD vs total mortality; genetic instruments capture small intake differences. None of these studies tests near-total elimination, and none addresses nutrient adequacy, which is the main concern for children and pregnancy.

这是否取决于国家？

一般生物学效应: Nutrient needs (fibre, folate, potassium, vitamin C) are universal.
饮食习惯: In Egypt, vegetables and legumes (ful, koshari, molokhia, salads) are central, affordable nutrient sources; removing them removes major folate and fibre sources.
食品原产地: not applicable
污染物: Residue concerns are addressed in C-VEG-13/14 and do not justify elimination.
本国生产条件: not applicable
法律规则: WHO and ESPGHAN recommendations apply.
实际监测数据: not applicable

足以改变结论的地区差异没有可靠数据支持。

统计复核

Log-symmetry of HR/RR CIs; illustrative absolute risk – CIs symmetric within rounding; at an assumed 10% 10-year risk, HR 0.87 would mean ARR 1.3% (NNT 77) if causal. 已重新计算
CI symmetry; interpretation of LR reduction – CIs consistent; 82-87% LR reduction indicates strong confounding of crude association. 已重新计算
Multiplicity of nominal stroke finding – OR 0.82 (0.69-0.98), p ~0.03, not significant after Bonferroni correction. 已重新计算

New evidence includes both directions: Wang 2021 strengthens the inverse association, while Feng 2022/2023 raise legitimate doubts about the size of the cardiovascular benefit. Neither changes the conclusion, because nutrient adequacy and guideline positions (WHO, ESPGHAN) are independent of that debate. Safety note sharpened for children.

通俗解释

Tayyibat 清单禁止几乎所有蔬菜、沙拉和豆类。大型研究一致地将多吃蔬菜、水果、膳食纤维和豆类与较低的心脏病、中风、某些癌症发生率和死亡率联系在一起。试验显示，膳食纤维、钾和豆类可以改善体重、血压和胆固醇。蔬菜和豆类也是叶酸的重要来源，而叶酸在孕前和孕期尤其重要。档案网站提到的特定风险，不需要放弃这些食物也能加以控制。

Vegetable benefit for the heart may be overestimated

Feng Q et al.. Front Nutr 2022 · PMID 35265657 · DOI 10.3389/fnut.2022.831470

队列研究独立交叉核查已核查摘要★ 关键研究

In 400,000 UK adults, raw vegetables were linked to 11% lower CVD risk, but adjustment for lifestyle and social factors explained over 80% of the association.

Suggests residual confounding of vegetable-CVD association; does not test near-total elimination.

一般科学评估

基本错误回避几乎所有蔬菜和豆类，与大量一致的证据和 WHO 的指导相矛盾；对心脏益处的大小存在争议，但营养素摄入不足是一种真实的风险，对儿童和妊娠期尤其如此。

以下食品安全领域与该说法相关：

农药与农药残留
污染物（重金属、PFAS、PCB、二噁英、硝酸盐）
真菌毒素（霉菌毒素）
病原体（沙门氏菌、弯曲杆菌等）
